慕尼黑一動物園打算利用動物糞便來發電供暖
2006-12-17
BERLIN (Reuters) - Animals at a Munich zoo will create their own power supply from Friday when their manure is recycled to generate heat and electricity.
據路透社12月13日報道,德國慕尼黑市一家動物園里的動物們將會從12月15日起在能源使用方面做到真正意義上的“自力更生”,因為該動物園的管理者已經決定將動物糞便加以循環利用來產生熱能和電力。
A biogas plant at the Muenchner Tierpark Hellabrunn will be fuelled by dung from elephants, rhinoceroses, buffaloes and antelopes, and any left-over animal food.
這家動物園已經在園內建好了一座沼氣發電廠,而其所用的燃料則包括大象、犀牛、水牛和羚羊等動物的糞便,以及任何動物吃剩的食物。
"Everything that animals with solid and cloven hooves eat which turns into manure goes into the plant," zoo director Henning Wiesner said on Wednesday."We‘ll also save ourselves a lot of lorry journeys we‘d otherwise have had to make to get rid of the manure, so it‘s doubly environmentally friendly."
動物園的園長海寧·維斯納說:“所有被那些蹄子結實的偶蹄動物吃進肚內并排泄出來的肥料都將會被運到發電廠里去。其實這樣做也使我們自己省了不少事兒,要不然的話,我們還得動用數輛卡車運輸多次才能夠將這些糞便清理出動物園,所以說這一舉措實際上具備了雙重環保意義。”
The plant, launched in co-operation with Munich city council, operates by fermenting the manure. This produces methane which is burnt to provide energy.
這座發電廠是由該動物園與慕尼黑市議會合作興建的,它的工作原理是首先將那些糞便發酵,待產生出甲烷后再將其燃燒即可獲取人們所需要的各種能源了。
Wiesner said it was too early to say exactly how much of the zoo‘s heating needs would be met by the plant but it should be a significant proportion. Animals at the zoo produce roughly 2,000 tonnes of dung a year.
據介紹,動物園目前尚無法準確估計這座發電廠能否滿足該動物園對熱能的需求,但這種能源供應方式最終所占比例應該是相當可觀的。這家動物園內的動物每年總共會產生出大約2000噸的糞便。[國際在線]
